-16 + 5n = -7(-6 + 8n) + 3   Given
-16 + 5n = 42 - 56n + 3   Distribute
-16 + 5n = 45 - 56n   Collect like terms
61n = 61   Add 56n to the left side and add 16 to the right side
n = 1   Divide 61 from both sides

The answer is n = 1. Remember that when you have a number beside two or more numbers in parentheses, you have to distribute, or multiply the number outside the parentheses by each number inside the parentheses.

Hope this helps!
